Directions
In a large non-reactive saucepan, combine the knotweed with the sugar and toss or stir to combine. Let the pan sit for about 15 minutes until the knotweed begins to seep liquid. Stir occasionally to help the process along.
When you start to see sugary juices forming, add the citrus zest and place the pan on medium-low heat and gently simmer, stirring occasionally, until the fruit is soft and falls apart, about the consistency of jam. This takes about 10 to 15 minutes.
Remove from the heat and transfer the compote to a bowl to cool. The compote can be eaten warm or cold, and is great on pancakes, waffles, ice cream and more. Makes about 2 cups.
